A Netlify Function failed to require one of its dependencies.

[twlite]

Hello, I started getting this error out of nowhere from today. It was working fine but it suddenly stopped working since last deploy.
While building, it throws:

5:15:45 PM:  > .netlify/functions-internal/next_api/nextPage/pages/api.js:166:34: error: Could not resolve "../webpack-runtime.js"
5:15:45 PM:     166 │ var __webpack_require__ = require("../webpack-runtime.js");

5:15:46 PM:   Build failed with 1 error:
5:15:46 PM:   .netlify/functions-internal/next_api/nextPage/pages/api.js:166:34: error: Could not resolve "../webpack-runtime.js"

I tried building my site locally as well but it throws same error.

After looking at the file .netlify/functions-internal/next_api/nextPage/pages/api.js:166:34, looks like it's trying to require ../webpack-runtime.js but there's a file webpack-api-runtime.js instead 🤔

This issue was fixed after removing lockfile & running yarn add -D @netlify/plugin-nextjs@beta
Looks like something messed up with the installation of @netlify/plugin-nextjs which caused this problem

This issue is that you still have the functions from the old version of the plugin. You should delete .netlify/functions-internal and rebuild. The next beta will check and warn for this.

@ascorbic How do we delete this ? Don't see controls for this on the Netlify admin panel

Clear the cache and deploy. If you have any next_ functions committed to netlify/functions then they should be deleted.
